We commonly encounter patients in the emergency department who present after a suicide attempt. The methods can vary and unique challenges depending on nature of an unsuccessful attempt via chemical ingestion that led to severe complications involving drain cleaner with both highly corrosive caustic properties. management presentation are discussed great detail further investigate best treatmen...

OBJECTIVE Caustic substance ingestion in childhood is a public health issue in developing countries, and several management protocols have been proposed to prevent the resulting esophageal strictures. The role of corticosteroids in preventing corrosive-induced strictures is controversial. Our aim was to study the influence of high doses of corticosteroids in preventing esophageal strictures. ...

Spatiotemporal measurements of a near-single-cycle terahertz pulse emitted from a photoconductive switch terahertz (THz) source show the effects of spherical aberration and surface waves on the pulse shape. The measured phase front has a swallow-tail shape described by catastrophe theory that contributes to the concentric ring structure of THz beam profiles. A time-of-flight model shows that th...

We present a method for the visualization of volumetric caustics in single-scattering participating media. The caustics beams are generated from a projected grid in light’s image space, making the solution independent from the geometric complexity of generators. The caustic volumes are extruded in the geometry shader and accumulated into the final volumetric effect.

Speaking for Dr. Greene's former students, I would like to extend our sympathy and warmest wishes to the Greene family. The essence of Harry Greene's life was a consistent search for what was true, real, and meaningful in life and science, with little concern for images. This led him to hold personal value standards that differed in some ways from those held by others. In his scale of values, h...
